Metra WM-GMK02 This stereo installation kit has been engineered to help you install either a 2” tall (Single-DIN) or a 4” tall (Double-DIN) aftermarket radio into the original vehicle dashboard. This dash kit makes radio replacement simple and comes with a pocket that is installed below the 2” radio to fill the extra space in the radio opening, which can be used for storage. The pocket is not needed when installing a 4” tall radio. The dash kit is designed to match the original look and feel of the vehicle’s dashboard in select 1990-2012 General Motors models. Installing an aftermarket radio can upgrade the sound quality and provide additional features the original factory radio couldn’t offer but requires this dash kit to make it fit.
